The purpose of this study was to evaluat the Zu, Cu, Mn and Ni status and correlation of their concentrations in serum, urine, hair and fingernail in female college studenst. As the results are follows; The mean age of subjects was 22.5 years and height, weight and BMI were 160.1 cm, 51.0 kg and 20.0 respectively. The daily intake of energy 1769.5 kcal and the ratio of carbohydrate, fat and protein for energy is 60:20:15. The daily intake of energy (88.5%), vitamin B2(86.1%), Ca(75.4%), Fe(58.3%) and Zn(63.0%) of subjects did not reach to Korean Recommended Dietary Allowance (RDA). The daily mean intake of Zn, Cu, Mn and Ni were 7.56 mg, 2.30 mg, 3.81 mg respectively. The concentarions of Zn in serum, urine, hair and nail were 85.6 micro g/dL, 391.2 micro g/day, 174.6 micro g/g and 102.4 micro g/g respectively and those of Cu were 84.2 micro g/dL, 56.6 micro g/day, 20.3 micro g/g and 4.3 micro g/g respectively. The concentrations of Mn in serum, urine, hair and nail were 0.2 micro g/dL, 1.1 micro g/day, 1.8 micro g/g and 1.6 micro g/g respectively and those of Ni were 0.6 micro g/dL, 24.5 micro g/day, 3.5 micro g/g and 3.1 micro g/g re-spectively. The daily intake of Mn showed the positive correlations with concentration of Mn in hair (p0.05) and the daily intake of Ni was positively correlated with urinary excretion(p0.05) and hair contents (p0.001) of Ni. The more detailed studies about these trace mineral status should be required.
